Revolutionary and rapid advances in computing hardware and software beginning in the 1970s not only had a profound impact on how the traditional, printed almanacs were produced and distributed, but also on the basic concept of what constitutes an alm

By coincidence, the two central solar eclipses of 1992 share a similar characteristic: both central paths will pass almost entirely over water, except for a very small portion at one end which will pass over land and include a major city. The first o

Since 1975, the Defense Mapping Agency (DMA) has been determining polar motion as a byproduct of computing the precise orbits of the Navy Navigation Satellite System (NNSS) satellites. The orbit determination process currently incorporates the NSWC 9

For more than a dozen years, Doppler tracking of the Navy Navigation Satellite System (NNSS) has demonstrated the ability to give solutions for polar motion as a byproduct of precise ephemerides generation. This paper reviews the polar motion estimat
